Gandalf vs Dumbledore

Author Comments

This is my entry to the jazza march challenge of the month, where I have drawn Gandalf the gray from lord of the rings to the left side vs Dumbledore from Harry Potter to the right.
In the background behind Dumbledore, we can see Howards, the school for magic. And in the background behind Gandalf we can see Minas Tirith, that it a castle we can see it the lord of the rings movies.

I appreciate feedback good/bad
Who do you think would win in a fight?
Dumbledore or Gandalf???
